MARTIN AUENSEN, OF CEMENT, CALIFORNIA.

ROTARY GAS-ENGINE.

Patented Aug. 5,1913.

Application filed. August 5, 1910. Serial No. 575,715.

To all whom it may concern:

Be it known that I, MARTIN AUENsEN, a citizen of the United States, residing atCement, in the county of Solano and State, of have invented new and useful Improvements in Rotary Gas-Engines, of which. the following is a specification.

This invention relates to hydro-carbon engines and particularly to rotary gas or gasolene engines.

The object of the invention is to cause the wings or pistons of the rotor to compress their own charges in a combustion chamber and then actuate a sparking lever to explode the charge thus compressed against the piston.

A further object of the invention is the provision of a rotor carrying a plurality of pistons which are adapted to actuate a combustion chamber valve whereby said valve is forced from its active position to permit the piston to take its place at the time of explosion. I

A further object (if the invention is the provision of a casing for rotating pistons with means for ventilating the piston throughout its rotation except at the points of compression and explosion.

Further objects of the invention will ap-' pear as the following specific description is read in connection with the accompanying drawing which forms t part of this application, and in which:

Figure 1 is a vertical sectional view. Fig. 2 is a similar view I Fig. 3 is a transverse vertical section. Fig. 4 is an end elevation of the engine. Fig. 5 is al detail vertical sectional View showing a modified form. Fig. 6 is a detail section taken on an irregular line through-Fig. 5.

In the specific embodiment of the invention illustrated herein 1 represents the cylindrical rotor casing which is bolted to the side plates 2 and is provided on its inner side with a cam-faced projection 3 having a diagonal end 4 in which is formed a pocket orromhustion chamber 5. Journaled in the side plates and passing centrally through the casing is the driving shaft 6 uponthe outer end of which is secured a suitable bal ance wheel 7 and keyed. to which is a rotor 8 which is concentrically mounted in the casing and is provided with a plurality of slots 9 in which are mounted the pistons 10. These pistons are constrnctedof separate showing a-difi'erent posi-v pieces of metal 11 and 12. the former of which is mortised at 13 and the latter of which is provided with a tongue 14 adapted to enter the mortise and be adjustable therein. A suitable spring 15 forces the parts of these pistons outwardly against the side plates so as to provide a tight joint between these parts. The pistons are preferably projected outwardly by means of springs 16 seated in the slots or recesses 9 so that the outer ends of the pistons are brought into engagement with the inner face of the casing 1. Suitable packing 17 is arranged in the ends of the pistons to provide a tight v,joint between the same and the inner side of the casing.

Secured to the outside of the casing adjacent its top is a-bearing bracket 18 in which is slidably mounted a gate valve 19 which passes diagonally through the aperture 20 in the casing and lies alongside of the face 4: of the projection 3 so as to close the combustion chamber 5 until displaced by one of the pistons. The valve 19 is normally pressed against the outer face of the rotor by means of a spring 21 and is adapted to be lowered into a socket 22 formed in the rotor so that the port 23 will register with the slot 24 formed in the valve whereby the combustion chamber may be blown out. The valve 19 closes immediately after the pistons pass the same by the action of the spring 21 which'also disconnects the contact parts as will be hereinafter described.

The outer ends of-the pistons are cut oif as at 25 so as to fit the diagonal face 4 of the projection 3 when they rise from their depressed position which is caused by the Cam faceof the projection. As these pistons rise to close the combustion chamber 5, the valve 19 is displaced and in rising contacts with a lever 26 which is pivoted upon an arm 27 carried by the bracket 18 and whose end is adaptedto be carried into engagement with a sparking rod 28 against the tension of the spring 21. The inlet port in the casing is shown at 29 and the outlet or exhaust port is shown at 30.

In the operation of the device, a suitable quantity of combustible mixture is drawn or forced into the inlet opening at 29 and is compressed into through a port 31 which is controlled by a check valve 32. As the piston passes-the end of the projection 3 and rises under the inthe combustion chamber 5 valve 19 and takes its place, thus maintaining a closed combustion chamber and the compression of the combustible mixture therein. Upon attaining its maximum height the valve 19 operates the lever 26 to contact with the sparking rod 28. This spark ing arrangement is not shown complete in itself as it may be of the make and break type controlled by the lever or it may be of the jump spark type and have the circuit completed by the lever. It is suflicient to state that the spark is produced within the combustion chamber at the time of its complete closure by a piston.

In order to cool the engine and produce a more efficient mixture therefor, the casing is provided with a plurality of openings 33 which extend at intervals around the same from the exhaust port to the inlet port. The pistons in their travel suck in a quantity of air which tends to cool the engine and a portion of said air is compressed in the combustion chamber, so as to combine with the gases and produce a more eflicient mixture.

In Figs. 5 and 6 the side members 2 are shown as provided with a s1o-t34 which is inclined upwardly for a predetermined distance and then is turned downwardly on the the point marked a: and cause'the piston to within the, combustion chamber, and means acting on said pistons to -move the same radially for closing the combustion chamber, whereby the charge when exploded will act upon the same to drive the rotor, and a valve for normally closing the combustion chamber which valve is displaced by the pistons.

2. In a rotary internal combustion engine, the combination with a casin having an inlet port therein, a combustlon chamber formed in the casing, a rotor mounted in the casing, a plurality of radially movable pistons carried by the rotor, means for projecting the pistons across the mouth of the combustion chamber, means forcontrolling the entrance of the charge tothe combustion chamber from the casing, and means displaced by the pistons for normally closing the combustion chamber.

In testimony whereof I afiix mysign'ature in presence of two witnesses.
